Plot Summary:New boss Robert Strickland asks the team to reopen the case of David Barrie, a barrister found dead, bound and gagged, in his car in the 1980s. The case was a rare instance of officer-in-charge Ronnie Ross's not getting his man. Chief suspect Michael, now a transsexual called Michaela, had an alibi, but Michaela is involved with Elaine Wanless, a former brothel-keeper who reveals the dead man's penchant for bondage. The team is convinced that both know more about the death than they claim.
